Title: Improvements in the manufacture of carbon black
IPC: C09C1/50
Filed: 1948-11-15
Abstract: <PICT:0652518/III/1> <PICT:0652518/III/2> Carbon black is produced by blasting a combustible mixture of fuel gas and oxygen-containing gas into one end of an elongated, unobstructed, heat-insulated chamber, burning the combustible mixture to form a high velocity, highly turbulent stream of blast flame gases, injecting a stream of hydrocarbon gas into the resultant stream in an amount in excess of that required to consume any excess oxygen and in a direction concurrent with and substantially parallel to the direction of flow of the flame gases, continuing the highly turbulent flow of the gas mixture through the chamber at a temperature sufficiently high to decompose the hydrocarbon, cooling and collecting the carbon formed. Methane with at least 10 per cent air is blasted from burner assembly 2, Fig. 2, into reactor 1 at 1900-2900 DEG  F. and methane, possibly enriched with higher hydrocarbons to more than 1200 B.Th.U. per cubic foot, which may be preheated to 500 DEG  F. is injected into the reactor through tubes 17.  The resultant gases flow, through the blending chamber 3 and passageway 4 wherein they are quenched by water sprays 11, to precooler 5, whence they pass to conventional cooling and collecting means.  The contact time between injection and first quenching should be 1/2 -1 sec. In the burner assembly 2, Fig. 3, methane under pressure is fed through pipe 24 and manifold 23 to jets 21 positioned behind burner ports 16 in refractory burner block 15.  Air under pressure is fed from air chamber 27a through perforated metal plate 31 into windbox 19.  The hydrocarbon passes through pipes 26 and manifolds 25 to refractory injection tubes 17 which are so arranged that each one is surrounded by burner ports 16. The manifolds 23, 25 may be longitudinally slidable to adjust the position of jets 21 and the protrusion of tubes 17.  The fuel and air may alternatively be premixed and the blast may be oxidizing, neutral or reducing.  Specification 402,322 is referred to.

Title: Control systems for selectively positioning electric motor-driven loads
IPC: G05D3/12
Filed: 1957-09-20
Abstract: 813,974. Control of D.C. motors; controllers; mechanical switches without quick action; actuation of switches. COLLINS RADIO CO. Sept. 20, 1957 [Feb. 21, 1957], No. 29687/57. Classes 38 (3) and 38 (5). Relates to a system in which a load 11, driven by an electric motor 13, is selectively positioned at one of five stations in accordance with the adjustment of a control lever 51 co-operating with a dial plate 52. To move the load from position 4 to position 1, a rotary switch 30 is turned to engage contact 31, and, at the same time, a toothed wheel 53 forces slide 57 against stop 59 whereby contact 64 of switch 60 is closed. A motor circuit is thus completed through field winding 29, and the load is driven to the left until it engages and opens the first switch 21 whereupon the motor is stopped at the desired position. If the load is required to be moved from position 4 to position 5, switch 30 is actuated to close contact 35, and wheel 53 forces the slide 57 against stop 58. This causes switch 60 to engage contact 63 and a circuit is established including reverse field winding 28. Thus, the load is driven in the opposite direction until it engages switch 25. As shown, a spring member 61 has one end fixed to the slide 57 and is formed with a tooth-shape to engage the wheel 53. Additional rotation of the wheel 53 after slide 57 has engaged an end-stop causes the wheel to slip over the member 61. The limits of movement of the slide correspond to the distance between two adjacent stator contacts of the switch 30. In a modification, rotation of lever 151 to position 2 causes wheel 153 to engage pin 155 on a spring-biased pawl 160. As a result, slot-end 159 is maintained in engagement with pin 156 whereby contacts 83, 84 are closed. Rotation of switch 130 closes contact 132 so that relay 72 is energized to close a circuit through the armature of the motor 113 and its single field winding 71. The motor continues to operate until a notch 126 in the rotor of a motor-driven switch 120 reaches stator contact 122. Movement of the lever 151 in the opposite direction effects closure of contacts 82, 85, so that the field winding 71 is reversed. Specification 660,939, [Group XXXVIII], is referred to.

Abstract: 1,154,809. Tubular heat exchangers. WAAGNER-BIRD A.G. 27 June, 1967 [27 June, 1966], No. 29693/67. Heading F4S. A multiple tube heat exchanger comprises a pressure tight shell 5 containing a parallel bundle of tubes 2 fixed in tube end plates 16 and 20, and an intermediate tube plate 21 which separates the heat exchanger into two effective portions, such that the cool medium 6 outside the tubes 2 flows co-currently to the hot medium 1 in the tubes in the portion 3 and countercurrently in the portion 4. In the embodiment shown, the medium 6 which enters the co-current portion 3 through a side entry 7 and leaves via an annular port 8 adjacent the pressure-tight shell 5, is conducted through passages 9 into a flow reversing header chamber 12 and hence into the counter-current portion 4, leaving the heat exchanger through the outlet pipe 13. At its entry into the co-current portion 3, part of the cool medium 6 is deflected and flows through a by-pass formed between the shell 5 and a radiation shield 11, said shield reducing the quantity of heat transferred by radiation from the portion 3 to the shell 5, thus cooling said shell 5. Radiation shields 10 are also used to help cool the shell in the counter-current portion 4. In order to improve the transfer of heat and to control the velocities of flow, baffles 18, 19 can be provided in the space around the tubes to convert the co-current portion 3 into a cross-co-current portion and the counter-current portion 4 into a cross-counter-current portion. The intermediate tube plate 21 which forms a tight sliding fit on the tubes 21, the shell 25 which forms the inner part of the channel 9, the baffles 19 and the outlet 13 for the medium 6 are freely movable in relation to the tube system 2. The tubes 2 are protected from differential thermal expansion by either a piston ring seal 24 or a knee bend (see Fig. 1). A thin gauge insulating plate 22 is located on the side of plate 16 facing the entering hot medium 1.
